Dear Kaveh, Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal. The presented object appears to be an etching print paper with 15 1/2 x 22 1/2 inches measurements. The print has an abstract motif and was made and signed by Wifredo LAM (1902-1982) . This motif comes from 9 illustrations for the book with the title "Contre une Maison Sèche" published by Jean Hugues in the year 1975. This print is not identical with the 9 published motif and is probably a draft for this series. Comparable objects were recently offered and sold on the international auction market. This piece is in good condition and no severe damage is visible in the images provided. A fair market estimation would be between 300 to 600 USD. This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary. With kind regards, George
